LM2660MM Equivalent & Substitute Parts

Part Overview

The LM2660MM is a charge pump switching regulator IC from Texas Instruments designed for power management applications. It provides positive or negative fixed output configurations with a single output delivering 100mA. The device operates across an input voltage range of 1.5V to 5.5V and supports multiple output voltage options (-Vin, 2Vin, Vin/2) with switching frequencies of 5kHz or 40kHz.

The LM2660MM is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LM2660MM is determined by strict equivalence across the following critical parameters:

• Topology & Function: Charge pump switching regulator with ratiometric function
• Output Configuration: Positive or negative fixed output capability
• Electrical Specifications: Input voltage range 1.5V to 5.5V, single 100mA output, switching frequencies of 5kHz or 40kHz
• Thermal Performance: Operating temperature range -40°C to 85°C (TJ)
• Package Compatibility: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) surface mount package
• Synchronous Rectifier: No synchronous rectifier present

The LM2660MM/NOPB qualifies as a direct substitute based on identical electrical specifications, package configuration, and functional characteristics. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The LM2660MM/NOPB is the direct substitute for the LM2660MM. Both parts share identical electrical and mechanical specifications, including input voltage range, output configuration, current capacity, switching frequency, operating temperature, and package format.

The LM2660MM/NOPB is classified as active product status, ensuring ongoing availability and supply chain support. Additionally, the LM2660MM/NOPB meets ROHS3 compliance requirements, whereas the original LM2660MM is RoHS non-compliant. Both parts maintain MSL Level 1 (Unlimited) moisture sensitivity classification and REACH Unaffected status.

Selection of the LM2660MM/NOPB is appropriate for new designs, production continuity, and replacement applications where the LM2660MM is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the LM2660MM/NOPB be used as a direct replacement for the LM2660MM?

A: Yes. The LM2660MM/NOPB is electrically and mechanically identical to the LM2660MM. Both parts feature the same input voltage range (1.5V to 5.5V), output configuration (positive or negative fixed), 100mA output current, switching frequencies (5kHz or 40kHz), operating temperature range (-40°C to 85°C), and 8-VSSOP package format.

Q: What is the primary difference between the LM2660MM and LM2660MM/NOPB?

A: The LM2660MM is classified as obsolete, while the LM2660MM/NOPB is active product status. Additionally, the LM2660MM/NOPB is ROHS3 compliant, whereas the LM2660MM is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both the LM2660MM and LM2660MM/NOPB use the 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) surface mount package with 8-VSSOP supplier device package designation. Pinout and footprint are identical.

Q: What does the "/NOPB" suffix indicate?

A: The "/NOPB" suffix indicates that the part is supplied without plumbum (lead-free). This designation is associated with RoHS compliance and environmental regulatory adherence.

Q: Is the LM2660MM/NOPB suitable for applications requiring RoHS compliance?

A: Yes. The LM2660MM/NOPB is ROHS3 compliant, making it suitable for applications and markets with RoHS regulatory requirements. The original LM2660MM is RoHS non-compliant.
